Replaced the ignitor, broken during conversion process from Natural Gas to Propane. I watched several YouTube videos for tips on completing task and there was no mention of being extra careful of the ignitor to avoid breakage, I have never seen an ignitor made of whatever this material is, but it appears to be fragile. I removed the broken part and practiced putting the burner back in without any ignitor in place. the way the burner goes in requires it to be hooked in the front and at the same time to go over the gas orifice and line up with the screw hole, (tricky). after a little practice I was able to install the burner and ignitor unit without any problems.
